The invention relates to railway cars and Vmorepart'icularly to means for manually operatingthe brakes thereof, and the principal object of the inventionfis toprovide aI novel B form of Ageared hand 'brake tachment to yfreight cars.

To this end the primary ,feature of the invention, generally stated, comprises a Vhand wheel rigidly fixed to a shaft, and a separate I0 shaft rotatably mountedon thefcar and connected to the brake lever-,by suitable :mecha- `nisrn and operatively connected to the first named shaft by alnovel arrangement of .inltermeshing gears.r f

Another feature of the linvention is to arrange a pair of `parallel shafts mounted off center with respect to each other, and to op-v eratively connect the shafts by suitable gearing and to locate it beneath thebrake step and invention applied thereto. c

The numeral l designates the end framing of a vfreight carto which is suitably connected, by means of .the bracketsf andthe brake step 3, a hand brake Awheel, 4 and asso- 59 ciated shaft 5.

inafter for convenience be referred to as the lowfpowered shaft. Fitting on va squared portion 6 of the low powered shaft 5 is a ratchet wheel?, and pivotally mounted in a conventional manner at a point adjacent to the ratchet ,is pawl 8 adapted to mesh with Y the ratchet ,7 ,and to preventethe'rotation thereof after thexapplication ofthe brakes. Thelpivot member 9 on which the'pawlS l,is mounted ,is gprov'ided with a lip lOadapted to .overlie the ratchet wheel 7 'to prevent the same from movingv upwardly from .the squared portion v6 .should thecotter pin Il()a be displacedor broken. Belowthe ratchet- 7'r the low powered shaft 5 is provided with a collar or cylindrical bearing portion l1 adapted to lit Withinthe bearing l2 suitably provided vin the brakestep. This collar ll may beconyeniently furnished with an internal squared portion adapted to slip :over the squared portion 6 ofthe shaft, and below thecollar `vll I provide Ythe lshaft V5 *with )a gear wheel 213 tixedly ymounted yon the said. shaft 1in-.any convenient vmanner, as forexaniple, byproviding the `saine with a rectangular, collar llt .adapted Ito lit .the squared portion 6 of thefsaid shaft.V e j n Tothe .lower side of thebrake, step I prof videabracket l5 which m ybe conveniently formed with a cylindrical opening 16, the said bracket having al downwardly deflected Y central 4portion 17 and beingV ,connected to the brake step' Bby means of thebolts '18. A,

second shaft l9'is rotatablymounted within the opening 16 and has'its lower end rotatably supported ina bracket 20 which depends fromfthe end sill 2l of the carframing l. The lower portion ofthe said bracket v'20 may be strengthened by Vproviding a tie YS22 riveted to the'lower portion of the bracket r20 and suitably connected to one of the center sills of the car. Intermediate'the bracket y 2O and the end sill 211 fixedl'y secure to the said shaft 1 9 a chain lever 23 having ay lever arm 23 .to which is connected inany suitablelmannerthe brake cha-m24. 'The' por?V tion of the high powered shaft beneath the lever is utilizedlas a chain drum, the lever f ar1n'2'3a acting as a quick take-upto gather up the slack at the first-half revolution of the high power shaft.

The portion of the shaft 19 which projects upward through the bearing 16 may be provided with a squared portion 25 to which is secured in any suitable way an internal toothed gear wheel 26, the teeth of the gear wheel 26 being adapted to mesh with the external teeth provided on the gear wheel 13, clearly seen in Figs. 3 and L1. rl`he gear wheel 26 is preferably closed on its lower side by the web 27, and intermediate the ribs 28 which reinforce and strengthen theweb 27, I provide openings 29 to permit the escape of water or other foreign substances which might become lodged within the gear wheel 26. j

In the arrangement shown the gear wheel 13, which is secured to the low powered shaft 5, is provided with half as many teeth as the gear wheel 26 which is fixedly connected to the high powered shaft 19. By this arrangement approximatelyT twice the force transmitted tothe low powered shaft 25 is transmitted to the brake chain 24C through the high powered shaft 19. It is to be understood, of course, that this arrangement of gear teeth is merely illustrative, and. I do not intend to limit my invention to this duplication of force, since it is obvious that larger or smaller gear wheels 13 could be advantageously employed and that in this way the force transmitted to the brake chain varied in accordance with the necessities of service.

It will be observed that the point of contact between the gear wheels 13 and 26 is on a transverse line which is substantially parallel to the end of the car. By this arrangement all danger of the gear wheels being locked together, due to either shaft being 'struck by the adjacent car, is avoided and the mechanism will also not be interlocled should the end framing of the car on which the same is mounted bulge as sometimes occurs due to severe shocks, shifting of the lading, overloading, and other causes.

Another feature of my invention resides in the ease with which-the device may be assembled with and removed from the car. For instance. incase of damage to the high power shaft. 19 the same may be readily removed without dismantling the mechanism by removingthe Cotter `30 which extends through the portion of the shaft below the bracket 20 and sliding` the shaft upwardly and then springing tl e lower portion of the shaft outof the bracket 20, the squared portion 25 there-of being removable downwardly from thegear wheel 25.

Another feature of my invention Aresides in the employment of thebralre shaft bearing 31 which may be, as shown particularly in Figures 1 and 2, formed as an angle iron with a vertical leg secured to the end of the car as by means of rivets 32 passing through the end sill 21, end plate 33 and, if desired, a filler piece 34, a horizontal leg 35 of said angle iron extending outwardly toward the shaft 19 and providing a semi-cylindrical bearing notch 36 opening outwardly as illustrated. Such a bearing provides for ready assembly and disconnection of the brake shaft with respect thereto and. it should be noted that, at the same time, it provides adequate support for the shaft as the pull of the chain' 24 is always in one direction. In freight cars subiect to end impacts, this type of bearing bracket is especially good for a heavy impact will often with a complete eye bearing bracket result in abent brake shaft. Furthermore, with the open or half eye, a bent shaft/will not be so serious in that it sweeps,
